For The Wrecks They Are A-Changin

The seabed and wrecks are dynamic environments. As divers we are not always aware of just how much things change unless something dramatic occurs. In 2012 the stern of the Karlsruhe was very ship-shape with neat lengths of teak decking in place. Then the stern winch capstan collapsed to the seabed and upended everything.

Scapa Flow – The Results

3D Work in Scapa At least once a year we take the long drive north to Orkney and Scapa Flow for a week of diving onboard the MV Valkryie. The Flow has been used as a military base during both world wars and the German High Seas Fleet was interred and scuttled there in 1919. Read more about Scapa Flow – The Results[…]

Let There Be Light

In the Beginning… In our temperate northern waters there is a lack of light. The very thing that underwater photogrammetry needs is often in short supply and light is like a drug. You always want more. Underwater photographers get around the limits of natural light with flash guns or video lights and these generally work Read more about Let There Be Light[…]

Underwater GPS and Photogrammetry

Where am I? Trying to scan underwater sites such as submerged landscapes or very broken wrecks often results in becoming hopelessly lost. Add into the mix the vision limiting experience of low visibility and a difficult job gets a lot harder. When on a sightseeing dive disorientation can be frustrating as you fin around missing Read more about Underwater GPS and Photogrammetry[…]

Photogrammetry Measurement and Scale

A Pretty Blob Photogrammetry is an excellent way to capture the world around us. Anyone can get involved and explore a subject that might otherwise be out of reach. The underwater world is such a place and with just 0.5% of the population able to dive bringing a shipwreck to the surface in digital 3D Read more about Photogrammetry Measurement and Scale[…]
